I'd like to see a thread about retro game prices. Sure it doesn't have to include every game (or every system) but some of the rare/ more expensive games. There are several sites that list rare games but usually you have to multi click through the site. So a thread that has a very good op would be a lot better.
Getting a forum on here would be an ideal place to stick it. Including how to care for retro systems and so on, and also conventions.
